From 74f84a5726c7d08c27745305e67474b8645c541d Mon Sep 17 00:00:00 2001 From: Pravin B Shelar Date: Mon, 17 Jun 2013 17:50:12 -0700 Subject: openvswitch: Copy individual actions. Rather than validating actions and then copying all actiaons in one block, following patch does same operation in single pass. This validate and copy action one by one. This is required for ovs tunneling patch. This patch does not change any functionality. Signed-off-by: Pravin B Shelar Acked-by: Jesse Gross Signed-off-by: David S.
